Some data fields in the scoring form, including turbinate and tonsil size, and use of adjunct airway, were not included in our analysis. LPW indicates lateral pharyngeal wall. Figure Legend:

Mean obstructive score at each of the 5 evaluated sites (adenoid, velum, lateral pharyngeal wall [LPW], tongue base, and supraglottis) is graphically represented as either less than 2.0 (white box) or 2.0 or more (black box). Multilevel obstruction group (1, 2, or 3) was defined as follows: Group 1: No or 1 site with obstructive score greater than 2; group 2: 2 or more sites with obstructive score greater than 2 but confined to upper (adenoid, velum, LPW) or lower (tongue base, supraglottis) airway complex; group 3: 2 or more sites with obstructive score greater than 2, encompassing both upper and lower airway complexes. Total indicates total obstructive score (sum of obstructive scores at each of the 5 sites) from sleep endoscopy. AHI indicates apnea-hypopnea index from preoperative polysomnography. Oxygen nadir is low oxygen saturation from preoperative polysomnography. Age in years, body mass index (BMI; calculated as weight in kilograms divided by height in meters squared), prior sleep surgery (N, none; A, adenoidectomy; or TA: adenotonsillectomy), and medical comorbidities (neuromuscular, syndromic, pulmonary, or chromosomal) are shown.

Ratings for minimum (light blue) and maximum (white) obstruction at each site are shown. 1.0 indicates perfect correlation; 0, no correlation. Error bars indicate 95% CIs for each measurement. LPW indicates lateral pharyngeal wall. Figure Legend:

Apnea- hypopnea index (AHI) and low oxygen saturation values for patients in the 3 multilevel obstruction groups were compared. Multilevel obstruction group (1, 2, or 3) was defined as follows: group 1, no or 1 site with obstructive score greater than 2; group 2, 2 or more sites with obstructive score greater than 2 but confined to upper (adenoid, velum, lateral pharyngeal wall [LPW]) or lower (tongue base, supraglottis) airway complex; group 3, 2 or more sites with obstructive score greater than 2, encompassing both upper and lower airway complexes. a P =.02.
